I'm trying to use sox in a AWS lambda function for conversion of FLAC file to MP3, but I cannot seem to build a version of sox with FLAC support.

I have found this great solution that I have been using but it doesn't support FLAC.

I've searched the net for alternatives but nothing seems to work. I've also read that at some stage FLAC support went missing but should have been fixed. I'm still looking for answers, but any help is appreciated.

You need to add the libvorbis and flac libraries to your static build and flag the sox build to include them. I have made changes to the script from your example questions to show you how this done.

    sudo yum update
    sudo yum install gcc44 gcc-c++ libgcc44 cmake –y

    # now grab sox and its dependencies
    mkdir -p deps
    mkdir -p deps/unpacked
    mkdir -p deps/built
    mkdir -p deps/built/libmad
    mkdir -p deps/built/sox
    mkdir -p deps/built/lame
    mkdir -p deps/built/libvorbis
    mkdir -p deps/built/flac
